The only one you mentioned I've had any contact with is the Ruger No.1. Belonged to my wife's uncle who I used to hunt with. It was a pleasure to shoot and fairly accurate. Chambered in 7mm.magnum and very light recoil. Probabaly had a fair bit to do with the weight of the rifle. As for single shots , have you looked at the Thompson Contender Prohunter? One of the nicest feeling rifles I've had on my shoulder. May actually put the Sako aside and try one.
